*For Thursday, 21 April 2011.

LEGEND for OVERVIEW: Size = My surety of area for quake.
Red Circle = Probable quake to STRONG quake.
Triangle = Very Strong/Stronger quake (Usually takes extra days).
Blue Circle, etc. = Uncertainty of symptom area for probable quake.
Gold Circle = Volcanic symptom.
(If I find a matching symptom in my database I will give a
probable magnitude.)

Places to watch.

Good luck to all.

For Thursday, 21 April 2011.
